I’ve been in several unions in the US. Generally they’re positive experiences and not something I’d denigrate. After having read your other comments in this thread, it would seem you and I would at best disagree. You give me the impression you’re a total mercenary with no other obligations other than enriching yourself. I am and know plenty of people who actually want to build community, build the commons, etc. Not saying that isn’t you, just saying from this thread I don’t have that impression.
You’re right of course, that super high performers don’t always benefit from a union. But the rest of us do when those folks have a sense of obligation to others.
I work to make money. My obligation there is to ethically make as much money as possible for my company, myself, and my employees.
I build community/commons/etc. in my personal time (which also includes some overlap since I do have some social relationships with work colleagues).
The amount of money I make at my job allows me dedicate more resources to those efforts, rather than intentionally docking my own pay to benefit some random person who happens to be performing a similar job to me much less effectively and would stand to benefit from being in a union.
